HYDRANT.

SPECIFICATION forming part of Letters Patent No. 681,901, datedSeptember 3, 1901.

Application filed June 13, 1901. Serial NOEBLLASG. (No model.)

To all whom it may concern,.-

Beit known that I, OWEN L. WHITEMAN, a citizen of the United States,residing at Coxsackie, in the county of Greene, State of New York, haveinvented certain new and useful Improvements in Hydrants, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

This invention relates to hydrants, and par- 1o ticularly to such astructure employing a movable gate-valve.

The invention has for an object to construct this valve and the guidingmeans therefor so that it shall be adjustable in dierent directions inorder to fit upon its seat and be clamped thereto when the valve isclosed.

A further object of the invention is to provide mea-ns carried by saidmovable valvegate for positively and automatically operzo ating adrip-cock to permit the escape of Water from the casing of the hydrant,which is necessary when the valve is closed upon the seat, and whichdrip-cock should be positively closed when the valve is opened to ad- 25 mit water into the hydrant-casing.

Other objects and advantages of the invention will hereinafter appear inthe following description, and. the novel features thereof will beparticularly pointed out in the ap- 3o pended claims.

In the drawings, Figure l is a vertical section through the hydrant withparts broken away. Fig. 2 is a horizontal section on the line 2 2 ofFig. 1. Fig. 3 is a rear elevation of the valve-disk of Fig. 2, with thecoverplate at the rear of the casing removed and also the connectionwith the valve-rod. Fig. 4 is a detail perspective of the nut adapted tobe carried by the valve-disk. Fig. 5 is a 4o detail elevation of thedrip-valve connection to be operated in the vertical movement ofl thevalve-disk, and Fig. 6 is a side elevation of the stem-nut. v

Like letters of reference indicate like parts throughout the severalfigures of the drawings.

In the drawings the letter A designates the vided with a cap A2,carrying any desired construction of valve-operating means adapted tovertically reciprocate the valve-rod B, which at its upper end isprovided with a threaded portion B' and at its lower end is connectedwith the valve-disk by means to be hereinafter described. For thepurpose of reciprocating this rod B the cover has applied thereto arotatable collar A3, having a wrench-hold at its upper end and athreaded portion A4 at its lower end, adapted to en-` gage the threadsB' of the valve-rod, which collar is suitably mounted in a packing-box,as shown. All of these features of construction, however, are well knownin the art and have not been very particularly described, as theinvention is in no wise confined thereto.

At the lower end of the valve-casing A the elbow O is applied and isprovided upon one face with the bearings C' for the valve-disk D andupon the opposite face with an opening C2, adapted to be closed by the'coverplate O3, which may be adapted to carry the drip cock or valve E.The inner face of this elbow is also supplied at opposite sides with4the guideiianges C4 at the upper portion thereof, tapering toward eachother and 4terminating at the upper ends of the guides C5, which areadapted to receive and guide the lugs D' at opposite sides of thevalve-disk D, so that the same may be withdrawn or inserted from theupper portion of the casing' and readily guided into position. Thecoverplate C3 is provided upon its inner face with a beveled or inclinedlug O6, which forms an abutment opposite the disk D in order that thesame may by the wedging action be forced into rm contact with its seatC'. The valve-disk D is carried by the stem-nut F, particularly shown inFig. 1t, which nut is provided at its lower portion with a curved faceF', adapted to seat in the socket D2, provided one face of the disk Dshould be secured Vtherein by means of a suitable device-'for instance,a set-screw D3, entering a recess in one end of said nut. Opposite thecurved face F' a wedging-face F2 is provided, which is curvedlongitudinally and at a right angle to the face F', while said face F2is also beveled slightly inwardly from the upper edge downward in orderto coperate in its wedging function with the lug C6. Extend- IOO ingupward from the center of the lower, portion of this nut is the'cylindrical stemkFg, adapted to travel within the socket D4 from theface of the disk D, which stem terminates in the threaded connection F4,by which the valve-rod B is secured thereto. It will be seen that thevalve is capable of oscillation in relation to the stem-nut in ahorizontal plane by reason ot' the socket D2, and the valve and nut areboth capable of oscillation in a vertical plane by reason of thethreaded connection between the nut and the valvestem B, while the nutis retained in its relation with the valve at all times by4 a setscrewD3. It will also be observed that the curved face F2 of the nut isadapted to rock upon the wedge-lug C, thus permitting the necessarymovement for the valve to accurately iit its seat, while the downwardpressure upon this face produces a wedging action to firmly hold thevalve in contact with its seat.

For the purpose of operating the drip-valve E, which may be of anydesired construction,

but is here shown as a rotating cock, I have provided upon one face ofthe valve-disk D a track or way G, which at its lower portion extends ina vertical plane and at its upper portion G' is curved into a horizontalplane, while the lower portion of this track or way is suitably tapered,as at G2, to permit the same to pass over an operating arm or lever II,extending from the drip-valve. This lever is provided with a crank-armH, carrying at its outer end a friction-roller H2, adapted to ride inthe way G, while the opposite end of the lever is provided with the 1perforated sleeve H3, adapted to tit over the apertured drip-pipe E',whereby the aperture in the collar H3 may be brought into alinement witha similar aperture in the drip-pipe lo permit the escape of water fromthe casing,vor when said apertures are thrown out of alinement thedischarge of water through such pipe will be stopped.

In the operation of the valve it will be seen that when the valve isopened by rotating 1 the -collar A3 the disk D will travel upwardbetween-the guides C5, and in its upward movement the lever from thedrip-valve will be thrown into a vertical position, as shown by dottedlines in Fig. 3, so as to close this valve and permit the discharge ofwater only from the hose connection A' of the casing. In the returnmovement to close the valve the disk travels downward, throwing thelever H into position shown by full lines in Fig. 3, so as to open thedrip-valve when the valve-disk D has reached its seat. During thisdownward movement the inclined face F2 of the stem-nut is riding incontact with the beveled lug C6, thus forcing or wedging the valve-disktoward its seat C. It will be further observed that the stem-nut has thetransverse horizontal extension thereof provided with the curved face Fextending transversely of the extension and the curved` face F2extending longitudinally of 'the extension. The first-mentioned facepermitsa rocking of the valve upon the stem-n ut, while the latterpermits a bodily rocking of the nut and valve upon the wedge-lu g, whilea movement of the valve-disk upon the rod B may be effected as beforestated.

It will be obvious that chan ges may be made in details of constructionand configuration of the several parts without departing from the spiritof the invention as defined by the appended claims.
